FIRE-EXTINGUISHER 2b all whom it may concern:

Be 1t known that 1, AUGUST C. Snnonn, a

citizen of the United States, residing at East St. Louis, in thecountyof St. Clair and State of Illinois, have invented new and usefulImprovements in Fire-Extinguishers, of which the following .is aspecification.

This invention is an improved automatic chemical sprinkler and firealarm for'extinguishingfires in buildings and at the the object of animproved.

same time sounding an alarm, theinvention being to provide apparatus ofthis class which is cheap and simple, is automatic in operation, ,whichrequi'ies little or no attention and which is eihcient and thoroughlypractical in use.

The invention consists in the construction, combination and arran ementof devices hereinafter described an claimed.

1n the accompanying drawings: Figure 1 is a vertical sectional View ofanautomatic sprinkler and fire alarm constructed in ac cordance with myinvention, showing the acid bottle and holder in-normal position in fulllines and in .overturned, operating position in dotted lines. Fig.2 isa'detail sectional view on the plane indicated by the line ar4 ofFig. 1. v

Referrin ,to the form of my invention e drawing a suitable-tank-l isprovided which in practice contains the usual soda solution. This tankhas a cap'2 at its upper end. .A delivery pipe 3 leads from the bottomof the tank to a sprinkler 4 Any suitable number of sprinklers may beemployed at different points and con-' nected to the said, includes afusible releasing element 5. A screen 6 is provided in the bottom of thetank and at theintake of the pipe 3. An electric enunciator 7 or othertranslating device is in circuit with a battery 8 and one of theconductors 9 is normally broken by a movable contact device 10 which isconnected by a suitable cord or wire 11 to the releasing element of thesprinkler head. When the said releasing element is fused or otherwisereleased it relaxes tension on the cord 11 and thereupon the circuit'isclosed at 10 and the alarm -sounded.

Thisbottle holder is here shown as cylindrical in provided with an opening16 in the bottom and as having spaced holder arms 17 at its upper endwhich are inturned toward one another. The trunnions 14 or pivots ofthe'bottle holder are to one side of the center of the bottle holder andon the bottle holder, near its bottle holder is released by the meansand hereinafter stated will cause the bottle,

A bottleor other container 19 for acid is arranged in the holder 15 andfloats therein on the soda solution in the tank and bolder andjthe mouth20 of the acid bottle or container isclosed by afixed stopper 21 whichis held by an arm 22. A sufiicient quantity of the solution ismaintained in the tank to keep the acid bottle raised so that its mouthis engaged and closed by the stopper 21 and this stopper also serves tohold the bottie holder in upright position and against thecounter-balancing tendency of the weight 18. When the sprinkler head isopened by 5 or otherwise flow the fusing of he alarm level to be loweredin the tank 1 and hence the acid bottle 19 becomes lowered and its mouthdisengaged from the stopper 21, whereupon the weight 18 overturns theholder 15 and the acid. bottle andcauses the contents of the acid bottleto be discharged intothe solution in the tank thereby generating gas anddis charging the same and the liquid from the sprinkler head andon thefire.
